The present study was carried out in laths house to study the effect of four levels of fertilizer (0.0, 1.0, 1.5 and 2.0) g as ammonium sulphate (21% N) and four levels of Phosphate fertilizer (0.0, 0.5, 1.0, 1.5) g as tri-super Phosphate (45% P2O5) per pot diameter 30 cm, mixed with soil surface on the vegetative growth and chemical content of Yucca aloifolia L. plants. The results refers that all studies parameters affected significantly by Nitrogen fertilization and Phosphate fertilization and the interaction between them on the concentration (2.0 gm/pot N with 1.5 gm/pot P) which total increased on height stem and leave number and stem diameter 13.44 cm and 11.61 leave and 2.98 cm in the end of study. While leaves area of plant and percent of chlorophyll and Nitrogen and Phosphor 2577.88 cm2 and 60% and 5.37% and 0.77% respectively in the end of study.
